Originally the tv picture would clear up after the tv was powered up for several minutes. I stopped using the television. I went to check on the television to see how long it would take for the picture to clear up to possibly sell the tv. The picture doesn't seem to clear up no matter how long it's on or from another input. I would like to know what it would take to fix this television.
Jansen6pack- I am currently repairing the same tv, what I found is that the video pak is going.I have checked pricing and the unit is about 500 bucks,but if you take it to a repair shop they may be able to repair it or send it away for repair. It may be worth the estimate charge. cooltekFeb.18/08

Sounds like the vertical controll circuit, it could just be a capicator that is on that circuit. as per the comb filter its very difficult to repair as the capacitors are micro and difficult to solder unless your soldering skills is very good. The is a place that repairs these comb filters www.ptscorp.com i am not sure at what cost though. At any case you can bypass the comb filter by
1.) getting an s-video adapter for your vcr
2.) connect the vcr to the tv using the s-video adapter
3.) change the channels using your vcr.
I'd rcommend you get a professional to have a look at it and repair it as it is much to difficult to repair your self even if you have the service manual
Since the comb filter is discontinued is will be best to bypass it by using the S-video input especially if you are on satellite receiver or use a composite to S-video adapter if you don't have dish. You might get the adapter at Radio Shack or shop online at Circuit City or Best Buy
It sounds that the main power regulator board has the fault. Try by replacing the electrolytic capacitors there. These capacitors can deteriorate its value with time. As the set is about 4 years old, this might be the fault. If it do not help you, replace the power regulator board as card basis.

This sounds like a heating problem..Either there is something keeping the heat inside the cabinet like stuff on top of the cooling vents (also on the sides and bottom) or there is dust inside. Blow the thing clean with clean, dry compressed air inside the cabinet.
o.k. check all your connections
if you have a newer house check to see if you have a main hub in a
closet somewhere and check all connections. Check your hd receiver and
you may be able to chage the DPI the receiver receives in.
I have this problem on some of my non HD channels, also. So much for going digital. I get fuzz and pixel problems "from time to time", but, if it is really bad and consistent your should call your service provider.
Things to ask also ? are you using cable or satellite.
If satellite T.V. there are other reasons you could be experiencing problems.
I also have a Hitachi 53SDX89BA and I bought it with the same assumption as you: that it's HD ready. The specs in the manual states the following: "Full 1080i HDTV Capatable with Set-Top Box". I beleive this means that it does not include an HD tuner, but that it is capable of handling up to 1080i resolution. Normal (non-HD) resolution on this TV is 480i.
So here's my problem: Until recently, I wasn't using the HD settings on this TV because I don't have a set top box, nor do I subscribe to any HD content from my cable provider. However, I just purchased an XBox 360 along with an XBox 360 HD-DVD player (it's an XBox peripheral that works with the game console). The Xbox asks you to choose the resolution output (480i, 720i or 1080i) to match your TV's HD capabilities. When I select 1080i output and change my TV's settings to receive an HD signal, the picture quality is amazing. However, the video signal seems to get lost ocassionally (i.e. TV picture gets scrambled) but then it comes right back. This does not happen when I select a 480i output on the Xbox...but of course, the picture isn't as crisp and clear as a 1080i picture.
I don't know if this is a problem with the TV or with the Xbox. Has anybody else had this problem??
